With the rapid development of manufacturing industry in recent years, the demand for metal processing has also increased. Welding is one of the important processes of metal processing, and the traditional welding methods have been unable to meet the demand of production. Under such a premise, the hand-held laser welding machine was born. Once launched, it was widely praised and quickly replaced the traditional thin plate welding market.

Laser welding machines are widely used in sheet metal processing, rail transit, automobile, engineering machinery, agricultural and forestry machinery, electrical manufacturing, elevator manufacturing, household appliances, grain machinery, textile machinery, tool processing, petroleum machinery, food machinery, kitchen appliances, sanitary ware, decorative advertising, laser external processing services and other fields.

The hand-held laser welding machine is a new generation of laser welding equipment, which belongs to non-contact welding. The operation process does not require pressurization. Its working principle is to directly irradiate the laser beam with high energy intensity on the surface of the material. Through the interaction between the laser and the material, the material is melted inside, and then cooled and crystallized to form a weld. The hand-held laser welding machine has subverted the working mode of the previous laser welding machine, and replaced the previous fixed optical path with the hand-held welding gun. This operation mode is not only more convenient for the welding of molds, advertising words, kitchenware, doors and windows, but also makes it possible to operate laser welding outdoors.

Handheld welding is mainly aimed at laser welding of long distance and large workpieces to overcome the limitations of the travel space of the workbench. When welding, the heat affected area is small, which will not lead to work deformation, blackening, and traces on the back. Moreover, the welding depth is large, the welding is firm, and the melting is sufficient. It can not only achieve thermal conductivity welding, but also continuous deep penetration welding, spot welding, butt welding, overlap welding, seal welding, seam welding, etc.

This process subverts the working mode of the traditional laser welding machine. It has the advantages of simple operation, beautiful weld, fast welding speed and no consumables. It can weld thin stainless steel plates, iron plates, galvanized plates and other metal materials, and can perfectly replace the traditional argon arc welding, stainless steel plates, iron plates, aluminum plates and other metal materials.

The hand-held laser welding machine is widely welcomed by the welding industry, and has good process characteristics in the welding process, so it is widely used in many fields. The hand-held laser welding machine is equipped with imported optical fiber, which is flexible and convenient, and can realize outdoor welding. The operation mode of the hand-held welding gun can weld the workpiece at any angle, and is suitable for spot welding of various complex welds and devices.

1. Simple operation, saving labor/material costs

It is easy to operate without professional welding technical experience. You can start the operation after 2 hours of simple training. Unlike traditional welding machines, which require professionals with operating experience, the use of hand-held laser welding machines can save the labor cost of employing professionals. The hand-held laser welding machine can basically achieve no consumables in the welding process and save costs in production.

2. Fast welding speed and high efficiency

Compared with traditional welding, the hand-held laser welding machine is super fast. One hand-held laser welding machine can basically replace the output of three to five ordinary welding machines. For enterprises, saving time means saving more money.

3. Good welding effect without grinding

The weld seam is bright and white after welding with hand-held laser welding machine, basically without grinding. The laser welding machine has concentrated energy, small thermal reflection range, products are not easy to deform, and the welding strength is very high. The energy and power of laser welding machine are digitally controlled, which can meet various welding requirements, such as full penetration, penetration, spot welding and so on.

4. Various welding materials

The hand-held laser welding machine can weld stainless steel plate, iron plate, galvanized plate, aluminum plate and other common metal materials.

5. Low requirements for processing environment

The hand-held laser welding machine does not need a special welding workbench. The equipment takes up small space and is flexible in processing. It is equipped with several meters of optical fiber extension lines, which can be moved for remote operation and is not limited by environmental space.

6. Sustainable work

The laser is equipped with water-cooling equipment to ensure continuous high intensity operation.

7. High cost performance

The hand-held laser welding machine can not only carry out welding operations, but also repair the mold, and can simply cut by replacing the cutting nozzle. The service life of the laser can reach 30 years, and it can be put into long-term use at one time with high cost performance.

8. High security

There are multiple safety alarms. The contact switch of the welding nozzle is effective only when it touches the metal. The light is automatically locked after the workpiece is removed, and the contact switch has temperature sensing. High safety to ensure the safety of operators during work.

Compared with traditional argon arc welding, hand-held laser welding machine has great advantages.

1. Energy consumption comparison: compared with traditional arc welding, the hand-held laser welding machine can save about 80%~90% of electric energy, and the processing cost can be reduced by about 30%.

2. Welding effect comparison: laser hand-held welding can complete welding of dissimilar steel and dissimilar metal. High speed, small deformation and small heat affected zone. The weld is beautiful, flat, free of/less porosity and pollution. The hand-held laser welding machine can carry out micro open type parts and precision welding.

3. Comparison of subsequent processes: the laser handheld welding has low heat input, small workpiece deformation, and can obtain a beautiful welding surface, without or only requiring simple treatment (depending on the requirements of the welding surface effect). The hand-held laser welding machine can greatly reduce the labor cost of huge polishing and leveling processes.

To sum up, laser welding machine This equipment can completely replace traditional welding equipment. Handheld laser welding has the advantages of simple operation, fast welding speed, beautiful and bright white weld, etc. It has been widely praised in the market and can perfectly replace traditional argon arc welding, electric welding and other processes.
